Airworthiness Directive · Amendment 39-8800 · Various Airplanes
Various Airplanes
This AD applies to Various F.28 Mark 0100.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F28 Mark 0100 series airplanes that requires replacement of the existing attachment bolts on the horizontal stabilizer with new, improved bolts having a longer fatigue life. This amendment is prompted by a report that certain attachment bolts on the horizontal stabilizer were not properly treated on the surface during production, resulting in reduced fatigue life. The actions specified by this AD are intended to prevent corrosion and subsequent fatigue-related cracking of the attachment bolts on the horizontal stabilizer, which could lead to loss of stabilizer control.
